MAS-100 ECO Portable Air Sampler

The MAS-100 ECO® Portable Air Sampler is a small, lightweight, NiMH battery operated sieve impaction system based on Anderson impaction to count airborne microorganisms. It is used for microbiological air monitoring in the hygienic production of food and cosmetics, as well as in the maintenance of ventilation and air-conditioning systems (HVAC). As an open system, the MAS-100 Eco sampler works with a wide variety of agar media in 90 mm Petri dishes, as well as other plate formats.

Air is aspirated through a perforated lid by a radial fan, controlled by a flow sense, that accurately regulates air flow in real time at the specified flow rate. The air is impacted on the surface of growth medium in a 90mm Petri dish. The MAS-100 ECO complies with the guidelines specified by ISO 14698 and EN 17141. The state-of-the-art mass flow sensor continuously ensures a constant air flow rate at a standard 100 liters per minute. Mass flow sensors allow samplers to automatically adjust for differences in the fill volume of Petri dishes, changes in air density, and differences between individual perforated lids. The instrument is delivered with a calibration certificate from an ISO 17025 accredited laboratory.
